Application September 19, 1939, Serial No. 295,553 9 2 (Cl. -133) 2 Claims.

- In carrying out my invention as herein embodied, I is the intermediate or center sheet or plate having a plurality of groups l6, II, II, l9, 2. and 2| of horizontally and. vertically arranged rectangular perforations of various lengths and said groups, for purpose of description, are separated by dotted lines, but these lines do not form operator of a vehicle is going to take in the manipulation of the vehicle.

Another object of this invention is to provide a number of perforated sheets in juxtaposition and constituting a signal, said sheets being shiftable lengthwise to produce a number of different indication signs.

, A further object of the present invention is to form a changeable signal by the use of a number of sheets each having perforations arranged to constitute a plurality of letters of the alphabet, said sheets being movable relative to one another to produce the desired letters in proper sequence for providing the preselected signal words or signs.

with the above and other objects in view, this invention consists of the details of construction and combination of elements hereinafter set forth and then designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part hereof, in which- Fig. 1 is a longitudinal sectional view of a lamp casing and holder for the signal sheets illustrating one way in which the latter may be used.

Fig. 2 is a cross section of Fig. 1.

Fig. 3 is a face view of the center sheet.

Fig. 4 is a similar view of the front sheet.

Fig. 5 is also a similar view of the back sheet.

Fig. 6 is a face view of the signal when all the shaats are in a neutral position to form the word s p") Fig. 7 is a similar view with the front or outermostsheet shifted towards the left hand end to form the word left.

\ Fig. 8 is the same kind of view with rear or innermost sheet shifted towards the right hand end to form the word "right."

Figs. 9, 10 and 11 are diagrammatic views to illustrate therelative positions of the sheets in forming the signs shown in Figs. 6, '7 and 8 respectively.

any part of the invention. The perforations in group ii are positioned in a manner to constitute elements of the letters "8 and B; group I1 constitutes elements of the letters L" and 1";

tangular perforations, said groups, for purposes of illustration only are shown in. the drawings as divided from one another by dotted lines. The perforations ingroup 22 include elements of the letters 8" and R; group 24, letters T, L"

and "I"; group 25, letters 0," E" and "G";-

group 26, letters P, F andH"; and group 21, the letter T."

0n the inside or in back of the intermediate or middle sheet or plate II is positioned the back or rear sheet or plate 28 which, like the other sheets, has a plurality or groups 29, 30, ll, 32, 33, I4 and I! of horizontally and vertically arranged rectangular perforations, said groups of perforations being plainly shown by the separating dotted lines used only for purposes of identifying the groups. The perforations in group 29 include elements of the letter B; group ll, elements of the letters 8" and "I"; group 3|, elements of the letters T, L and "G"; group 32, elements of the letters "T" and "E; group 33, elements of the letters "0" and "H"; group 34, elements of the letters fO," "F and T; and group I5, elements of the letters T" and P.

The sheets or plates II, 22 and 28 are mounted in any suitable manner for sidewise longitudinal movements relative to one another to selectively register the groups of perforations having related characteristics in two or more of the sheets to produce letters of different words having different sign or signal significance or directional meaning. Illustrative of one method of accomplishing the mounting and movements of the sheets is shown in Figs. 1 and 2 wherein 1. represents a lamp housing having suitable sources of light :1, such as electric lamps, and in nest of said housing are slides or tracks 32 in which the sheets or plates are mounted in the relation speciiied. -In front of the sheets or plates maybe located a panel 29 of glass or other transparent or translucent material. This panel is preferably colored or provided with a ground or frosted surface so as to be translucent whereby light rays from the source of light passing through the registered perforations of the sheets will a visible signal word on the panel.

The sheets ll, 22 and 22 may be moved in several different relations, for instance, the outer sheet 22 may be moved to the left while the sheets "and it remain stationary or said sheet 22 may be held stationary and the others moved in unison to produce one signal. With the sheets then in such offset or staggered relation the sheet produce 28 may be moved to the right While the sheets A convenient method of changing the relation of the sheets is to mount the middle one in a stationary position and make the front and rear sheets movable so the front sheet can be moved to the left from a neutral position and back as desired and the rear sheet can be moved to the right from a neutral position and back. This can be accomplished manually or automatically through the medium of mechanism including rods II, or wires or other equivalents attached to the sheets 22 and 22 as shown in Fig. 1.

When all of sheets 22, I! and 28 are in a neutral position as shown in Fig. 6 and illustrated diagrammatically as in Fig. 9, the groups of perforations having the characteristics of the letters 81' T, "0 and P" will be in alignment and from the signal word stop. When thesheets are'so positioned that the front or outer sheet 2: is to the left of the other two catedinl 'igs. 8 and 11.

In every instance when the signal words are formed the perforations which are not needed.

to produce the desired and selected letters are blanked out by imperforate areas of some of the sheets.

From the foregoing it will be apparent that of the appended claims without departing from the spirit of my invention. 7

Having described my invention, what I claim asnew and useful is;

1. A directional signal comprising three sheets arranged one'behind another, the inner or rear sheet having groups of perforations disposed to form-some of the characteristics of the letters S and R; T, L and I; 0, E and G; P, F and H; and T; the intermediate or middle sheet having groups of perforations disposed to form some of the characteristics of the letters S and R; L and I; T, E and G; O; 0, F and H; and P and T; the front or outer sheet having groups of perforations disposed toform some of the characteristics of the letters R; S and I; 'I', L and G; T and E; O'and H; and 0, F and T; two of the sheets being movable longitudinally wherebythe groups of perforations having the same characteristics may be brought into alignment, in a selected manner, to produce desired signal words.

2. A directional signal comprising three sheets arranged one behind another, the inner or rear sheet having groups of perforations disposed to form some of the characteristics of certain letters of the alphabet; the intermediate or middle sheet having groups of perforations disposed to form I I complete letters appear when they are brought in certain relative positions, two of the sheets being movable longitudinally whereby thegroups of perforations having the same characteristics may be brought into alignment, in a selected manner, to produce desired signal words.
